SHADE-HOLDER.

Specification of Letters Patent.

Patented. Apr.13, 1915.

Application filed April 2, 1912. Serial No. 688,078.

to an improved means for attaching the shade to the support, whereby theshade will be readily attached and detached and at the same timesecurely held against danger of accidental release of the clamping meanswhich would permit the shade'to drop out.

According to this invention, I provide in combination with a supportorshell of wellknown form a contractible ring which is provided withcamor screw means between its extremities for contracting and expandingthe ring to clamp or release the shade, the ring itself having aplurality of points 'of support in the shell which prevent the 7 ring orany portion thereof from disengaging from the shellor accidentallyopening.

In the accompanying drawings, Figure 1 y is anelevation of a shadeholder embodying the invention; Fig. 2 is a vertical section; and Fig. 3is a horizontal section taken on the line 3, 3 of Fig. 2. v

1 represents the shell or support having f a bushing 52 preferablythreaded therein, by which the shell is attached to the lamp fiX- ture,and 3 represents the shade, reflector or other device which is to besupported.

4 represents a clamping ring which is resilient, and which is adapted tobe contained, when expanded, in the bead 5 of the'shell 1. The shell isprovided with perforations 6, preferably three in number, disposedsubstantially equally apart, through which lugs or bent portions 7, 7 ofthe ring 4 are inserted, and also the ends 8, 8 of the ring, therebyinterlocking the ring and shell against vertical movement, or relativerotation. These lugs 7, 7 and the ends 8, 8 support the ring in theshell, it being seen that the ring carries the weight of the shade. Thlugs 7, when bent in the ring, alsoadd resiliency. By means'of thesedifferent in: terlocked points of support the shade will be securelyheld when the ring is properly contracted. i

In order to contract the ring, I provide means acting independentlyofthe shell, and preferably carried wholly by the ring, such as a cam ordouble screw 9, which is threaded through nuts 10, swiveled in the ends8 of the ring 4 so that the threads will not bind as the ring iscontracted or expanded. To clamp the shade, its upper end would beinserted within the ring whenex panded, and the ring contracted untilthe shade is firmly clamped. This permits various sizes of shades to beeffectually clamped. .Itwill be seen that accidental disengagement willbe av'oided,as the ring cannot warren snares PATENT oration.

so I

open by anyshock or jar, and, moreover, it

is operated by a single. clamping device.

Having. thus described my invention, I declare that what 'I claim as newand desire to secure by Letters Patent is:

A shade holder comprising a tubular depending support, formed at itsupper end to receive a lamp socket or the like. and en-' larged at itslower end to receive the flange of a shade, said lower portion having aplurality of circumferentiallv extending slots, a shade gripping ringwithin said support having intermediate projections and its endsextending outwardly through said slots and movable therein to center thering and shade in the support. and a screw carried by said ring endsoutside the support and having. opposite threaded engagement therewithfor positively expanding and contracting the ring.

In testimony whereof I aflix my signature in presence of two witnesses.

Witnesses: C. V. EDWARDS,
